Purpose: The purpose of this study was to evaluate the radiological and clinical outcomes of tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail for patients with complex hindfoot problems, including Charcot arthropathy, osteonecrosis of talus, combined arthritis of the ankle and subtalar joint, failure of previous ankle arthrodesis, and failed total ankle arthroplasty.
Materials and Methods: Eighteen consecutive patients (10 men and 8 women) with an average age of 54 years (range, 42~72 years) underwent tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail fixation. The mean duration of follow-up was 16 months (range, 12~23 months). Radiological evaluation included assessment of the union status of ankle and subtalar joints. Clinical evaluations included visual analogue scale (VAS) for pain and patient satisfaction, and postoperative complications were analyzed.
Results: Radiological union was achieved in 14 ankle joints (77%) and 16 subtalar joints (88%) at an average of 16 weeks (range, 14~40 weeks) and 14 weeks (range, 12~24 weeks), respectively. The preoperative VAS were 4.6 (range, 4~8) at rest and 8.2 (range, 7~10) during walking, and the postoperative VAS were 2.2 (range, 0~3) and 4.6 (range, 4~6), respectively (p<0.05). There were 6 nonunions (4 ankle joints and 2 subtalar joints), 3 tibia fractures, 2 delayed union of ankle joints, and 2 breakage of the implant.
Conclusion: Tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail may be considered as a viable option in patients with complex hindfoot problems.
